Dist Ubuntu Esm H88
Numerous vulnerabilities addressed in Ubuntu 22.04 LTS impacting the Linux kernel and OEM configurations. Ensure your system is updated!
Several security issues were fixed in the Linux kernel.

Summary

Several security issues were fixed in the Linux kernel.

Software Description:

- linux-oem-5.17: Linux kernel for OEM systems

Details:

David Leadbeater discovered that the netfilter IRC protocol tracking

implementation in the Linux Kernel incorrectly handled certain message

payloads in some situations. A remote attacker could possibly use this to

cause a denial of service or bypass firewall filtering. (CVE-2022-2663)

It was discovered that the IDT 77252 ATM PCI device driver in the Linux

kernel did not properly remove any pending timers during device exit,

resulting in a use-after-free vulnerability. A local attacker could

possibly use this to cause a denial of service (system crash) or execute

arbitrary code. (CVE-2022-3635)

It was discovered that the network queuing discipline implementation in the

Linux kernel contained a null pointer dereference in some situations. A

local attacker could use this to cause a denial of service (system crash).

(CVE-2022-4...

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.04 LTS:
   linux-image-5.17.0-1035-oem     5.17.0-1035.36
   linux-image-oem-22.04           5.17.0.1035.33
   linux-image-oem-22.04a          5.17.0.1035.33

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
